you can create portfolio items like posts. Go to Portfolio Items > Add New and enter title, text, etc. by using the wordpress text editor.

2) You can add images by using the “Add featured media” options field. Click on “Upload” to upload images, videos, etc. To add more images/videos/slides to the slideshow click on the green plus symbol (bottom right corner). You can delete the slide with the red X.

Think got another problem. In the Welcome/Home page of the template, the Half texts under the main slideshow doesn’t have margin, but something change in my template that the now have margins and it forces the right half to fall under the first one. heres the link so you can see http://www.r2roweb.com
